This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert HashTrieMap creates persistent mappings and supports insert, remove, discard, get, update, and convert
  2. assert HashTrieMap raises KeyError when accessing or removing missing keys
  3. assert HashTrieSet creates persistent sets and supports insert, remove, discard, union, intersection, difference, and symmetric_difference
  4. assert HashTrieSet raises KeyError when removing missing elements
  5. assert List creates persistent linked lists and supports push_front, drop_first, first, and rest
  6. assert List raises IndexError when accessing first or calling drop_first on an empty list
  7. assert Queue creates persistent FIFO queues and supports enqueue, dequeue, peek, and is_empty
  8. assert Queue raises IndexError when calling peek or dequeue on an empty queue
